Where the floats are symmetrically positioned in relation to the middle of the carb, I wouldn't have thought that would make any significant difference?

Obviously with a single or twin choke carb the float chamber is usually to the front and this provides a degree of mixture enrichment under acceleration or uphill and leans out in the reverse situation.

As a matter of interest I had planned on mounting my BG 825 RS Race Demon back to front just to simplify the throttle linkage.

Anyone got any good reasons why I shouldn't? Jac Mac?

Hey Russ, are you ready for this!! In your application with the manifold you intend to use it will be OK--- provided you fit the the rear float bowl assy to the other end and vice versa along with jet extensions if fitted. This is due to the front rear bowls being configured to different fuel levels.
In the edelbrock carb above I think it will have larger secondary bores which could foul on the manifold @full throttle. Also as the floats are hinged at the rear (from memory) & would now be changed to front hinge in this application ,fuel level characteristics may be a problem. Like most things in life you wont know if you dont try.
